Sacrament of First Communion
There are a number of good resources to be found from the United States Conference of Catholic Bishops’ website, including these:
Eucharist: Body of Christ, Broken for the World – United States Council of Catholic Bishops
The Fountain of Love: How Parents Form Children for Eucharist – United States Council of Catholic Bishops
Unbaptized children, over the age of reason (7), are to become part of the parish-based Rite of Christian Initiation for Adults (RCIA) with adaptations for children. Children who have reached the age of reason are considered, for purposes of Christian initiation, to be adults (Canon 852:1). Their formation should follow the general pattern of the ordinary catechumenate as far as possible. They should receive the Sacraments of Baptism, Confirmation, and Eucharist at the Easter Vigil, together with the older catechumens. Contact the Office of Sacramental and Family Life with questions about children in the catechumenate or call (716) 847-2207 for more information about the RCIA.
